Numerical Simulation of Running Resistance of an Amphibious Weapon

In this paper, the commercial software CFD was used to solve problems by solving the Navier-Stokes equatlon with the model and VOF method. Firstly, the author computed and simulated the sailing of the experimential amphibious weapon running on the water. Secondly the resistance results reasonably compared with the test data from the towing tank, showing that the technology can play an important role in the research of fluid dynamic performance of an amphibious weapon, At the same time, an apparent discrepancy in conculated and test results at high speed shows that the application or parameter itself should be improved.
